Cisco Systems 5505 Optional Allowing Access to Public Servers Behind the ASA, ASA 8.2 and Later

7. (Optional) Allowing Access to Public Servers Behind the ASA

ASA 8.2 and Later

The Public Server pane automatically configures the security policy to make an inside server accessible from the Internet. As a business owner, you might have internal network services, such as a web and FTP server, that need to be available to an outside user. You can place these services on a separate network behind the ASA, called a demilitarized zone (DMZ). By placing the public servers on the DMZ, any attacks launched against the public servers do not affect your inside networks.

Step 1 In the main ASDM window, choose Configuration > Firewall > Public Servers. The Public Server pane appears.

Step 2 Click Add, then enter the public server settings in the Add Public Server dialog box. (For information about any field, click Help.)

Step 3 Click OK. The server appears in the list.

Step 4 Click Apply to submit the configuration to the ASA.

8. (Optional) Running VPN Wizards

You can configure VPN using the following wizards:

•Site-to-Site VPN Wizard—Creates an IPsec site-to-site tunnel between two ASAs.

•(ASA 8.0 and later) AnyConnect VPN Wizard—Configures SSL VPN remote access for the Cisco AnyConnect VPN client. AnyConnect provides secure SSL connections to the ASA for remote users with full VPN tunneling to corporate resources. The ASA policy can be configured to download the AnyConnect Client to remote users when they initially connect via a browser. With AnyConnect 3.0 and later, the client can run either the SSL or IPSec IKEv2 VPN protocol.

•(ASA 8.0 and later) Clientless SSL VPN Wizard—Configures clientless SSL VPN remote access for a browser. Clientless, browser-based SSL VPN lets users establish a secure, remote-access VPN tunnel to the ASA using a web browser. After authentication, users access a portal page and can access specific, supported internal resources. The network administrator provides access to resources by users on a group basis. ACLs can be applied to restrict or allow access to specific corporate resources.

•IPsec (IKEv1) Remote Access VPN Wizard—Configures IPsec VPN remote access for the Cisco IPsec client.

Step 1 In the main ASDM window, choose Wizards > VPN Wizards, then choose one of the following:

•Site-to-Site VPN Wizard

•AnyConnect VPN Wizard

•Clientless VPN Wizard

•IPsec (IKEv1) Remote Access VPN Wizard

Step 2 Follow the wizard instructions. (For information about any wizard field, click Help.)

10. (Optional) Configuring the IPS Module

ASA 8.2 and Later

If your ASA came installed with a Security Services Card (SSC), you can use ASDM to set up the SSC and configure the Intrusion Prevention System (IPS) application to run on the SSC. An SSC does not have any external interfaces.

Step 1 In the main ASDM window, choose Configuration > Device Setup > SSC Setup. The SSC pane appears.

Step 2 Complete the SSC setup fields and click Apply. (For information about any field, click Help in the dialog box.)

Step 3 To configure the IPS module on the SSC, click the Configure the IPS SSC module link. The Startup Wizard appears. Click Launch Startup Wizard. (Alternatively, you can choose Configure > IPS > Sensor Setup > Startup Wizard to access the wizard.)

For more information about configuring the IPS module, see the IPS module quick start guide on Cisco.com.
